Release Notes: Error backtraces include line numbers and filenames. FileDescriptor is now a subclass of Stream, and the old superclass ByteStream has been removed. Some functions exported by the VM to plugin modules are now thread-safe. Stream operations try to eliminate useless copies and garbage collections when moving data from stream to stream. Support for imports was added to namespaces. The sockets package was renamed from TCP to Sockets as it now supports IPv6 and AF_UNIX sockets (in the Sockets package). Bindings to OpenGL and GLUT were contributed.
Release Notes: This is a minor release, mostly consisting of bugfixes in network-related packages. It also includes improvements to the Emacs smalltalk-mode, fixes for platforms with 113-bit long doubles, and fixes to the C binding mechanism. The parser for the Squeak/Pharo format was updated.
Release Notes: Many bugs were fixed. gst-package supports downloading from HTTPS URLs. You can optionally specify a timeout when waiting on a Semaphore. SCGI support was added in the Swazoo Web server. Virtual machine performance was improved on x86-64. Starting from these release, bundled libraries (libsigsegv, libffi, libltdl) are never preferred over pre-installed libraries.
Release Notes: This release included fixes to gst-remote and the Emacs mode. Generational GC did not work on the SPARC and is now disabled. When compiling a 32-bit version on a 64-bit system, detection of which packages can be installed was improved.
Release Notes: This version includes mostly portability and testsuite improvements. Notable are bugfixes to the graphical interface (VisualGST) and to UDP sockets.
Release Notes: Remote packages can be downloaded for smalltalk.gnu.org hosted projects. A new browser based on GTK+ was added. A callgraph profiler was added. Incremental garbage collection was implemented. Many other changes were made.
